  • energy columns with high height and cantilevered elements like those in FIG. 9 to be seen lamps 54 are included in the mounting box according to the invention, it is recommended that these as in FIG. 7 shown in detail, support directly on the bare soil and instead dispense with the claws to provide no coupling between the unfinished soil and the floor slabs or screed.
  • the mechanical connecting element 12 has an internal thread 29 as a receptacle for a socket 30.
  • the pedestal 30 has a stand rim 28 which can be screwed to the unfinished floor by means of holes and slotted holes.
  • the stationary rim 28 is connected to a cylindrical support 32 via three supports 31 extending upwardly from the stationary rim 28 and radially inwardly.
  • the cylindrical support 32 has an internal thread into which a base tube 33 is screwed with external thread 34. On the upper end of the base tube 33, the mechanical connection element 12 and thus the mounting box 1 is screwed with the internal thread 29.
  • the height of the mechanical connecting element 12 can be set freely selectable.
  • the upper edge 15 of the housing 2 is aligned so that it terminates approximately level with the upper edge of the screed or the bottom plate of the double or cavity floor. If the height adjustment has taken place, the screw connection is clamped with the aid of grub screws or grub screws and the height adjustment is blocked.
  • FIGS. 10 to 15 show a fitting of the mounting box according to the invention in a reduced form. This is used when the recessed box is not to be used as a base for energy distributors, but merely as a simple floor outlet for connection cable.
  • FIGS. 10 to 15 are all elements that come with the elements from the FIGS. 1 to 9 identical are denoted by identical reference numerals.
  • FIGS. 1 to 9 Compared to the FIGS. 1 to 9 is the recessed box in the FIGS. 10 to 15 not equipped with a mechanical connection element. Instead of the mechanical connecting element, only a guide sleeve 56 is received on the first receiving portion 6 of the housing 2, which provides the same functionality as the guide sleeve 35 in the assembly of the FIGS. 1 to 4 , That is, the outer wall 57 of the guide sleeve 56 is identical as the outer wall 36 of the guide sleeve 35 from the FIGS. 1 to 4 ,
  • the guide sleeve 56 has a second receiving portion 58, with which in this assembly of the connector carrier 59 is connected. Between the second receiving portion 58 and the connector carrier is a spacer element, here a spacer ring 60 is arranged, which allows depending on the choice of its thickness, the plane in which the connector carrier is disposed inside the housing 2, to choose freely.
  • FIGS. 16 and 17 A third alternative way to equip the installation box according to the invention is in FIGS. 16 and 17 shown schematically.
  • the mounting box has neither a connector carrier nor a guide sleeve for a cover.
  • the mounting box 1 serves only as an outlet for cables from a cavity or raised floor.
  • the housing inner wall 4 has a ring-shaped circumferential groove 61 as a lid receptacle into which corresponding latching lugs 62 of the cover 64 engage.
  • FIG. 16 is again clearly visible that the claws 24 are added later to mount the mounting box on a flat construction element in the corresponding receptacles of the housing 2.
  • FIG. 18 shows an alternative embodiment of the mounting box according to the invention 1 'with a housing 2', wherein in addition to the receptacles 27 'for clamping claws in the housing through holes 70 are provided. These through holes 70 penetrate the cylindrical housing 2 'and extend from the housing inner wall 4' to the housing outer wall 3 '.
  • the through holes in the illustrated embodiment form an angle with the cylinder axis 71 of the housing 2 '.
  • a spacer screw 72 is screwed through the through-hole 70 into the double bottom plate 73 surrounding the mounting box 1 '.
  • the spacer screw 72 is a spacer screw having a thread extending the full length of the constant-pitch screw 72. Therefore, the spacer screw 72, without forces in the radial direction would act on the mounting box 1 ', in the housing 2' and in the raised floor plate 73 screw. If the mounting box 1 'with the help of the captured clamping claws (in FIG. 18 not shown) clamped to the raised floor plate 73, the spacer screws act 72 after screwing as an abutment for the clamping claws. The claws and the spacer screw together form a triangle viewed from the side.
  • FIG. 18 It is clearly recognizable in FIG. 18 a distance between the support surface 20 'of the cover 19' at the upper end of the housing 2 'from the top 74 of the raised floor plate 73. This distance remains constant after screwing the socket 1' with the raised floor plate 73. All moments exerted on the mounting box 1 'are introduced via the spacer screw 72 directly into the raised floor plate 73 and the claws.
  • FIG. 19 shows an alternative method of installation of the socket 1 'from FIG. 18 in a cavity floor.
  • the cavity floor shown consists of a support plate 75 and a screed 76 cast thereon, wherein the mounting hole for the mounting box 1 'is kept free of a mold 77 during the casting of the screed 76.
  • This formwork form 77 in turn forms a mounting box 1 'concentric and annular surrounding dowels. The fitting of the mounting box 1 'with the cavity floor 75, 76 takes place in this dowel 77.
  • the design of the dowel 77 as an annular element allows the cavity socket 1' before screwing in the hole in the cavity floor 75, 76 rotate arbitrarily and align and then screwed into the dowel 77 in this arbitrary position by means of the spacer screws 72.
  • the plug is used in the completion of the screed as a shell body.
  • it has a lid, which is cut or removed after completion of the screed. Then the mounting box 1 'is inserted into the hole, the clamping claws are tightened and thus the height and inclination of the can 1' set. Only then are the spacer screws 72 screwed through the mounting box 1 'and in the dowel 77.
  • the dowel 77 extends over the entire assembly height of the cavity floor 75, 76, it allows a "height adjustment" of the mounting box 1 ', since this at any distance between the support surface 20' of the cover 19 'and the cavity floor 75, 76 and Dowel 77 can be screwed.
  • the built-in box 1 ' is installed in a conventional floor with a floating screed78.
  • the dowel 77 is poured into the wet screed, but he sits in the illustrated embodiment on a terminal box 79, which is also cast into the screed and allows a cable feed through corresponding connected to the terminal box empty pipes in the socket 1 '.
  • two extension elements 80, 81 are provided between the terminal box 79 and the dowel 77, which provide height compensation between the upper edge of the terminal box 79 resting on the bare floor and the dowel 77.
  • the terminal box 79 with the first Aufstockelement 80, this in turn with the second Aufstockelement 81 and the second Aufstockelement 81 with the dowel 77 is locked.
  • the extension elements can also be screwed together.
  • the construction of the dowel 77 is particularly clear from the three-dimensional view of the arrangement FIG. 23 to recognize.
  • the floating screed 78 is off FIG. 20 omitted, so that circumferentially arranged teeth 99 can be seen on the outside of the dowel 77, with which the dowel with the screed 78 is engaged.
  • FIG. 21 and 22 show alternative embodiments of the socket 1 'from FIG. 18 , wherein instead of a mechanical connecting element 12 with a self-centering cone for easy detachable recording of an energy column mounting elements 90 and 92, 93 are connected to the receiving portion 6 'of the housing 2'.
  • FIG. 21 shows a mounting member 90 which is screwed to the lower part of an energy column 94 by means of holes 95, 96 cross-screws.
  • the mounting member 90 in turn is connected to the receiving portion 6 'of the housing 2' of the socket 1 'connectable.
  • FIG. 22 shows FIG. 22 the inclusion of a combination of two mounting elements 92, 93 on the receiving portion 6 of the housing 2 'of the mounting box 1' to the mounting box 1 'with a receptacle 97 for a summarizeramades tube 98 as a support element, for example, for a floor lamp, a camera, a projector or a touch panel to connect.
